Hi Stefano,

i changed the line you suggested and ran the job again:

Now it crashes after several thousand events, leaving me with the following stacktrace:

evt 60200
evt: 60300
evt 60300
evt: 60400
evt 60400
evt: 60500
evt 60500

 *** Break *** segmentation violation

Root > Function simfast_opt() busy flag cleared


Every time I run it, the crash occurs after a different number of events. This may be due to the fact that I cannot generate the _same_ events again, using exactly the same random seed (can I??).

How to deal with this error?

Best regards,
Malte
